How to implement Error handling in Openscript

Question

Hi All,
Please help me to implement this .
I am creating Load test script for ebs - approve requisitions process. 
The script will login to check any requisitions are waiting for approval, if found then it will click on random requisitions then approve it.  
There are no requisitions for approval then I want to call the log-out function then start the iteration again.
What function to be used to start the iteration again .
//After login, I am checking no of requisition to approve.
beginStep("Login");
getScript("MyFunc").callFunction("ebsLogin");
  http.assertText("LoginCheckString", "window[@index='0']","Oracle Applications Home Page", Source.Html,TextPresence.PassIfPresent, MatchOption.Exact);
  try {                          
  http.solve("noOfFound", "window[@index='0']", "<a id=\"N39:(.+?)\" title=\"Purchase Requisition ", "No Requisitions Found", false, Source.Html, null, EncodeOptions.None);
  }catch (Exception e){
  info("No Requisitions to Approve");                                              
        getScript("UtilityFunc").callFunction("ebsLogOut"); 
  // I want to start the iteration again after this point, but it's continue executing the remaining steps.
endStep();
beginStep("ClkRequisitions");
  http.link(716,"window[@index='0']//a[@id='N39:{{sRndChoice}}']").click();
endStep();
beginStep("Logout");
getScript("UtilityFunc").callFunction("ebsLogOut");                
endStep();

Create a flag(boolean) and loop till true, ie.
boolean flag =true;
while(flag){
---your steps----
try{
----your steps---
flag=false;
catch(Exception e){
---your steps---
